It looks like...
Hi hazy,
It looks like a "put together" movement.
For ref 2520 a cal. 352 would be correct. Special finished parts (ratchet wheel, regulator) are OK for the cal 352.
But what the heck is with the plate with inscription "354" - somebody must have swapped this part for an unknown reason...
I would recommend to request an extract from the Omega archive to see if the movement number is correct for this case,
might give some more information about what happened to the watch.
regards

Seamaster Chronometre restoration
Hi everyone, I inherited this watch a long time ago but I never paid close attention to it as I felt too young to wear a gold watch. I have rediscovered it recently along with its green box and after some research, I believe it is a solid 14k gold case 25...
Dial is correct; crown probably later replacement
For service: Full movement service with replacement of parts as needed Light case polish Leave dial alone
Shorter hands
Shorter hour and minute hands with a black second hand would be nice. Best.
At some point..........
in its past, the minute and second hand (at least) have been replaced - the hands should just touch the chapter ring. Personally, I would restrict restoration to a good clean up of the case and movement with the latter serviced as needed and a new crystal...
Leave the watch...
Hi, I suggest to do as little as possible (and necessary ) to the watch. 1) Cleaning and re-lubrication of the movement 2) removal of scratches on the crystal and polishing it afterwards 3) replacement of the wrong winding crown (not difficult to obtain) ...
will know more in a few weeks
thank you all for your very appreciated contributions, I was a little hasty and have already left it at omega for a restoration estimate which is gona take a couple months... I insisted that I wanted the dial to remain untouched. If they end up being too ...
omega is not really the solution for restoring such a watch
Hi I think that a very experienced local watchmaker can do the job but you must check that he is someone who is working very long years as a watchmaker ((btw the same way that he has an experince with vintage Omegas) and not some young guy who just finish...
I agree with Msnwatch and Mac_Omega...
Hi That is one of my favorite omega dials. The patina of the dial is also stunning... I have seen that style only a few times before... Please let us know what happens Best BIll Sohne
Omega estimate received
I just received the estimate for Omega's "full maintenance service" with replacements of parts as needed, quoted at 800ish € with a 16 weeks delay. the estimate list the watch serial as 12280XXX and the calibre as 354 I m a bit puzzled as according to the...
I think...
they have quoted the number from the inner caseback and not from the movement. I have yet to see a cal. 354 movement with a serial number under 13 million. On the other hand at this time of production, the inner caseback number is lower by ~1 million comp...
Thank you for your response MSNWatch
So the watch is on the way back from Omega and I m going to have a local shop do the work you guys suggested. Is the consensus to replace the hands for shorter ones? which colors should the sweep seconds be? It s hard to tell from the pictures I posted bu...
..
I was hoping with the update, it would be finished pictures after the restoration. Looking forward to seeing how this one turns out. The sentimental value that it belonged to your grandfather, along with the great condition of the original dial is a doubl...
Case opened!
Finally got the watch back from Omega... brought it to a local guy and asked him to open it and here s what I found... 354 with AR system a 12M serial and I think deluxe finish wheels??? it s a 2520 case with an 11M serial. I bought a deployant from omega...
It should not be a 354 in there
The rest of the movement including the serial is ok for a cal. 352 except for the piece with the cal. 354 stamped on it. Yes, crown can be sourced from ofrei - these are easy to get there.

internet wonders...
www.oldwatch.club.tw If you look at the watch on this page the case number and movement number are both a single digit away from mine so without requesting an extract I think the case and movement match. I guess the most likely explanation is that the "po...
My thoughts
Crystal and crown for this watch easily sourced from ofrei. Hands a different story - you'll have to measure (from center right to the edge of the minute track to get the minute length hand correct. And even then you'll have to match the lume. Frequently,...
Weren't some cal 354s issued as chronometers? . . .
. . . that's my recollection, at least, from one of Bill's earlier postings . . .
Not all of them
Not all of 354's were manufactured as chronometres, lots of non chronometre 354's were used to power the seamasters, too.
Granted, and my understanding is there's far more . . .
. . . cal 354s without chronometer rating than with, but wouldn't the acknowledged existence of some chronometer rated 354s tend to validate this example?
Problem with this example
is that other parts like the regulator are from a cal. 352 and not from a 354. The movement serial number which is in the 12 million range also belongs to a cal. 352. So a 354 mark in the movement is incorrect.
I don´t think so...
Hi Hoi, I don´t think that Omega made a mixture of 2 calibers, it seems very unlikely to me. kind regards Erich
Hands are very hard to find.
Totally agree with Mike. The most difficult thing to do is to find that part that has 352 on it. Then come the hands, first, you measure the hands with a caliper then ask the seller of item # 130652535338 to see if those hands are right for you. But don't...
finally
This crown tube opening is too big so another one is on its way from ofrei, it is still missing a 352 barrel bridge, and It will look better on an Omega gold deployant than on the steel one I have... But it s finally on my wrist so I m very happy today! F...
Lovely watch
But, as i,m sure you know, its not a pie pan dial. Wear with pride Cheers, paul
